2023-09-18perf jevent: fix core dump on software events on s390Thomas Richter1-1/+1
Running commands such as # ./perf stat -e cs -- true Segmentation fault (core dumped) # ./perf stat -e cpu-clock-- true Segmentation fault (core dumped) # dump core. This should not happen as these events are defined even when no hardware PMU is available. Debugging this reveals this call chain: perf_pmus__find_by_type(type=1) +--> pmu_read_sysfs(core_only=false) +--> perf_pmu__find2(dirfd=3, name=0x152a113 "software") +--> perf_pmu__lookup(pmus=0x14f0568 <other_pmus>, dirfd=3, lookup_name=0x152a113 "software") +--> perf_pmu__find_events_table (pmu=0x1532130) Now the pmu is "software" and it tries to find a proper table generated by the pmu-event generation process for s390: # cd pmu-events/ # ./jevents.py s390 all /root/linux/tools/perf/pmu-events/arch |\ grep -E '^const struct pmu_table_entry' const struct pmu_table_entry pmu_events__cf_z10[] = { const struct pmu_table_entry pmu_events__cf_z13[] = { const struct pmu_table_entry pmu_metrics__cf_z13[] = { const struct pmu_table_entry pmu_events__cf_z14[] = { const struct pmu_table_entry pmu_metrics__cf_z14[] = { const struct pmu_table_entry pmu_events__cf_z15[] = { const struct pmu_table_entry pmu_metrics__cf_z15[] = { const struct pmu_table_entry pmu_events__cf_z16[] = { const struct pmu_table_entry pmu_metrics__cf_z16[] = { const struct pmu_table_entry pmu_events__cf_z196[] = { const struct pmu_table_entry pmu_events__cf_zec12[] = { const struct pmu_table_entry pmu_metrics__cf_zec12[] = { const struct pmu_table_entry pmu_events__test_soc_cpu[] = { const struct pmu_table_entry pmu_metrics__test_soc_cpu[] = { const struct pmu_table_entry pmu_events__test_soc_sys[] = { # However event "software" is not listed, as can be seen in the generated const struct pmu_events_map pmu_events_map[]. So in function perf_pmu__find_events_table(), the variable table is initialized to NULL, but never set to a proper value. The function scans all generated &pmu_events_map[] tables, but no table matches, because the tables are s390 CPU Measurement unit specific: i = 0; for (;;) { const struct pmu_events_map *map = &pmu_events_map[i++]; if (!map->arch) break; --> the maps are there because the build generated them if (!strcmp_cpuid_str(map->cpuid, cpuid)) { table = &map->event_table; break; } --> Since no matching CPU string the table var remains 0x0 } free(cpuid); if (!pmu) return table; --> The pmu is "software" so it exists and no return --> and here perf dies because table is 0x0 for (i = 0; i < table->num_pmus; i++) { ... } return NULL; Fix this and do not access the table variable. Instead return 0x0 which is the same return code when the for-loop was not successful.

2023-08-29perf jevents: Use "default_core" for events with no UnitIan Rogers1-1/+1
The JSON Unit field encodes the name of the PMU to match the events to. When no name is given it has meant the "cpu" core PMU except for tests. On ARM, Intel hybrid and s390 the core PMU is named differently which means that using "cpu" for this case causes the events not to get matched to the PMU. Introduce a new "default_core" string for this case and in the pmu__name_match force all core PMUs to match this name.

2023-08-25perf jevents: Don't append Unit to descIan Rogers1-7/+0
Unit with the PMU name is appended to desc in jevents.py, but on hybrid platforms it causes the desc to differ from the regular non-hybrid system with a PMU of 'cpu'. Having differing descs means the events don't deduplicate. To make the perf list output not differ, append the Unit on again in the perf list printing code. On x86 reduces the binary size by 409,600 bytes or about 4%. Update pmu-events test expectations to match the differently generated pmu-events.c code.

2023-08-24perf jevents: Group events by PMUIan Rogers1-45/+136
Prior to this change a cpuid would map to a list of events where the PMU would be encoded alongside the event information. This change breaks apart each group of events so that there is a group per PMU. A new table is added with the PMU's name and the list of events, the original table now holding an array of these per PMU tables. These changes are to make it easier to get per PMU information about events, rather than the current approach of scanning all events. The perf binary size with BPF skeletons on x86 is reduced by about 1%. The unidentified PMU is now always expanded to "cpu".

telemetry repo Apart from some slight naming and grouping differences, the new metrics are functionally the same as the existing ones. Any missing metrics were manually appended to the end of the auto generated file. For the events, the new data includes descriptions that may have product specific details and new groupings that will be consistent with other products. After generating the metrics from the telemetry repo [1], the following manual steps were performed: * Change the topdown expressions to compare on CPUID and use #slots so that the same data can be shared between N2 and V2. Apart from these modifications, the expressions now match more closely with the Arm telemetry data which will hopefully make future updates easier. * Append some metrics from the old N2/V2 data that aren't present in the telemetry data. These will possibly be added to the telemetry-solution repo at a later time: l3d_cache_mpki, l3d_cache_miss_rate, branch_pki, ipc_rate, spec_ipc, retired_rate, wasted_rate, branch_immed_spec_rate, branch_return_spec_rate, branch_indirect_spec_rate [1]: https://gitlab.arm.com/telemetry-solution/telemetry-solution/-/blob/main/data/pmu/cpu/neoverse/neoverse-n2.json Signed-off-by: James Clark <james.clark@arm.com> Reviewed-by: John Garry <john.g.garry@oracle.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andrii Nakryiko <andrii@kernel.org> Cc: Eduard Zingerman <eddyz87@gmail.com> Cc: Haixin Yu <yuhaixin.yhx@linux.alibaba.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jing Zhang <renyu.zj@linux.alibaba.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mike Leach <mike.leach@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Nick Forrington <nick.forrington@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Rob Herring <robh@kernel.org> Cc: Sohom Datta <sohomdatta1@gmail.com> Cc: Will Deacon <will@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Link: https://lore.kernel.org/r/20230816114841.1679234-7-james.clark@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2023-08-17perf vendor events arm64: Update stall_slot workaround for N2 r0p3James Clark1-4/+4
N2 r0p3 doesn't require the workaround [1], so gating on (#slots - 5) no longer works because all N2s have 5 slots. Use the new expression builtin that allows calling strcmp_cpuid_str() and comparing CPUIDs in metric formulas. In this case, the commented formula looks like this: strcmp_cpuid_str(0x410fd493) # greater than or equal to N2 r0p3 | strcmp_cpuid_str(0x410fd490) ^ 1 # OR NOT any version of N2 [1]: https://gitlab.arm.com/telemetry-solution/telemetry-solution/-/blob/main/data/pmu/cpu/neoverse/neoverse-n2-r0p3.json Signed-off-by: James Clark <james.clark@arm.com> Reviewed-by: John Garry <john.g.garry@oracle.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Eduard Zingerman <eddyz87@gmail.com> Cc: Haixin Yu <yuhaixin.yhx@linux.alibaba.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jing Zhang <renyu.zj@linux.alibaba.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mike Leach <mike.leach@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Nick Forrington <nick.forrington@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Rob Herring <robh@kernel.org> Cc: Sohom Datta <sohomdatta1@gmail.com> Cc: Will Deacon <will@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Link: https://lore.kernel.org/r/20230816114841.1679234-6-james.clark@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2023-08-17perf jevents: Add a new expression builtin strcmp_cpuid_str()James Clark1-2/+15
This will allow writing formulas that are conditional on a specific CPU type or CPU version. It calls through to the existing strcmp_cpuid_str() function in Perf which has a default weak version, and an arch specific version for x86 and arm64. The function takes an 'ID' type value, which is a string. But in this case Arm CPU IDs are hex numbers prefixed with '0x'. metric.py assumes strings are only used by event names, and that they can't start with a number ('0'), so an additional change has to be made to the regex to convert hex numbers back to 'ID' types.

2023-08-03perf build: Update build rule for generated filesNamhyung Kim1-0/+6
The bison and flex generate C files from the source (.y and .l) files. When O= option is used, they are saved in a separate directory but the default build rule assumes the .C files are in the source directory. So it might read invalid file if there are generated files from an old version. The same is true for the pmu-events files. For example, the following command would cause a build failure: $ git checkout v6.3 $ make -C tools/perf # build in the same directory $ git checkout v6.5-rc2 $ mkdir build # create a build directory $ make -C tools/perf O=build # build in a different directory but it # refers files in the source directory Let's update the build rule to specify those cases explicitly to depend on the files in the output directory.

2023-07-11perf vendor events amd: Fix large metricsSandipan Das3-3/+6
There are cases where a metric requires more events than the number of available counters. E.g. AMD Zen, Zen 2 and Zen 3 processors have four data fabric counters but the "nps1_die_to_dram" metric has eight events. By default, the constituent events are placed in a group and since the events cannot be scheduled at the same time, the metric is not computed. The "all metrics" test also fails because of this. Use the NO_GROUP_EVENTS constraint for such metrics which anyway expect the user to run perf with "--metric-no-group". E.g. $ sudo perf test -v 101 Before: 101: perf all metrics test : --- start --- test child forked, pid 37131 Testing branch_misprediction_ratio Testing all_remote_links_outbound Testing nps1_die_to_dram Metric 'nps1_die_to_dram' not printed in: Error: Invalid event (dram_channel_data_controller_4) in per-thread mode, enable system wide with '-a'.

Introduce a new metricgroup, Default, to tag all the metric groups which will be collected in the default mode. Add a new field, DefaultMetricgroupName, in the JSON file to indicate the real metric group name. It will be printed in the default output to replace the event names. There is nothing changed for the output format. On SPR, both TopdownL1 and TopdownL2 are displayed in the default output. On ARM, Intel ICL and later platforms (before SPR), only TopdownL1 is displayed in the default output.

2023-06-16perf metric: JSON flag to default metric groupKan Liang6-76/+114
For the default output, the default metric group could vary on different platforms. For example, on SPR, the TopdownL1 and TopdownL2 metrics should be displayed in the default mode. On ICL, only the TopdownL1 should be displayed. Add a flag so we can tag the default metric group for different platforms rather than hack the perf code. The flag is added to Intel TopdownL1 since ICL and ADL, TopdownL2 metrics since SPR. Add a new field, DefaultMetricgroupName, in the JSON file to indicate the real metric group name.
